Find Java local variable writes

Recipe IDio.moderne.prethink.FindJavaLocalVariableWrites

Artifactio.moderne.recipe:rewrite-prethink

Report written initializers and bare-target simple assignments for regular block locals in their own ordinary method, with original declaration, variable, write, target and direct RHS identities, raw nullable types and source ranges. Preserve individual declarator order, repeated and nested write sites, explicit binding states and direct RHS roots without unwrapping. Excludes fields, formals, lambda-body locals, captures and constructor or initializer bodies; nested ordinary methods own their locals. Does not change sources, evaluate RHS values or infer reaching definitions, taint or runtime flow.

Data tables

Java local variable writes

io.moderne.prethink.table.JavaLocalVariableWrites

Written INITIALIZER or SIMPLE_ASSIGNMENT sites for supported regular block locals in their own ordinary method. Retains original declaration, individual variable, write, target and direct RHS identities and ranges, raw nullable types, occurrence multiplicity and explicit binding states. Unknown or ambiguous bindings retain written site facts with null declaration cells. No initializer evaluation, reaching-write selection, value identity, taint or runtime-flow inference.

Column	Description
Source path	Actual Java compilation-unit source path.
Source set	Actual sole JavaSourceSet name; null for missing or ambiguous source-set markers independently of project markers. Preserve empty values.
Project ID	Actual sole JavaProject marker UUID; null for missing or ambiguous project markers. Never normalize, borrow or identify by project name.
Project name	Actual sole JavaProject name, descriptive only; preserve null and empty independently of source-set markers.
Source set ID	Actual sole JavaSourceSet marker UUID; null for missing or ambiguous source-set markers independently of project markers.
Source file ID	Actual compilation-unit UUID in the externally verified original VCS, commit, model-input and producer namespace. Equal CU IDs alone do not prove nested-node identity.
Declaration ID	Actual J.VariableDeclarations wrapper UUID for a safely RESOLVED supported local binding. Null for UNRESOLVED or AMBIGUOUS; no synthetic identity.
Variable ID	Actual individual NamedVariable UUID for a safely RESOLVED local binding. Multiple declarators have distinct IDs sharing the real wrapper; never a JavaType.Variable object identity.
Variable type	Opaque observed declaration JavaType.toString for a RESOLVED binding; null for missing or whole Unknown type and unsafe bindings. Never parse or substitute RHS/use type.
Variable start line	Full actual individual NamedVariable start, including any initializer and excluding enclosing type or semicolon. One-based line; null unless binding is RESOLVED.
Variable start column	Full actual individual NamedVariable start from unchanged Coordinates. One-based UTF-16 column, tab one, CRLF-aware; null unless binding is RESOLVED.
Variable end line	Exclusive full actual individual NamedVariable end. One-based line; null unless binding is RESOLVED. Initializer syntax does not establish a value.
Variable end column	Exclusive full actual individual NamedVariable end from unchanged Coordinates. One-based UTF-16 column, tab one, CRLF-aware; null unless binding is RESOLVED.
Write ID	INITIALIZER uses the actual NamedVariable.id; SIMPLE_ASSIGNMENT uses the actual J.Assignment.id. Tagged original node identity, never a synthetic write UUID.
Write kind	INITIALIZER for a supported local with a non-Empty written initializer; SIMPLE_ASSIGNMENT for exactly J.Assignment with a whole bare Identifier LHS naming a supported in-scope local. No reaching-use selection.
Write start line	Whole actual NamedVariable start for INITIALIZER or whole J.Assignment expression start for SIMPLE_ASSIGNMENT. One-based line; no trailing statement semicolon or generated coordinate.
Write start column	Whole actual write-node start from unchanged Coordinates. One-based UTF-16 column, tab one, CRLF-aware.
Write end line	Exclusive whole actual write-node end: NamedVariable or J.Assignment expression, excluding a trailing statement semicolon. One-based line.
Write end column	Exclusive whole actual write-node end from unchanged Coordinates. One-based UTF-16 column, tab one, CRLF-aware.
Target ID	INITIALIZER uses the actual bare declaration-name Identifier.id; SIMPLE_ASSIGNMENT uses the actual bare LHS Identifier.id. A declaration token is not a read reference; writeKind distinguishes the roles.
Target name	Actual target Identifier spelling metadata. Name alone never establishes declaration binding or a cross-table join.
Target start line	Actual target Identifier token start from unchanged Coordinates. One-based line; not a generated name span.
Target start column	Actual target Identifier token start. One-based UTF-16 column, tab one, CRLF-aware.
Target end line	Exclusive actual target Identifier token end. One-based line.
Target end column	Exclusive actual target Identifier token end. One-based UTF-16 column, tab one, CRLF-aware.
RHS ID	Actual direct getInitializer() or getAssignment() expression UUID. Preserve parentheses, cast, assignment, lambda and new roots; never substitute an inner invocation ID.
RHS kind	Stable direct AST kind label: Identifier, FieldAccess, MethodInvocation, NewClass, NewArray, Literal, TypeCast, Parentheses, Assignment, AssignmentOperation, Binary, Unary, Ternary, Lambda, MemberReference, ArrayAccess, InstanceOf or Other. No lazy-proxy class names or unwrapping.
RHS type	Opaque actual direct RHS JavaType.toString; null for missing or whole Unknown. Actual literal-null type text may be the string null. Never replace with declared local type, FQN or an effective runtime value; no RHS/declaration type equality requirement.
RHS start line	Actual direct RHS expression start from unchanged Coordinates. One-based line; wrappers retained, no guessed or generated range.
RHS start column	Actual direct RHS expression start. One-based UTF-16 column, tab one, CRLF-aware.
RHS end line	Exclusive actual direct RHS expression end. One-based line; no inner-expression substitution.
RHS end column	Exclusive actual direct RHS expression end. One-based UTF-16 column, tab one, CRLF-aware.
Binding state	RESOLVED for a safely bound supported actual local, UNRESOLVED for unavailable or conflicting metadata, or AMBIGUOUS for multiple surviving distinct candidates. Unsafe bindings null all seven declaration cells while retaining real write, target and RHS facts.
Binding reason	UNIQUE_LOCAL_DECLARATION, BINDING_UNAVAILABLE, CONFLICTING_ATTRIBUTION, MULTIPLE_LOCAL_CANDIDATES or UNSUPPORTED_BINDING_LAYOUT. Initializer association is structurally its own NamedVariable; neither a state nor a reason establishes values, execution, reaching definitions or taint.
