Constructor Details

ForEachStmt

public ForEachStmt()

ForEachStmt

public ForEachStmt(VariableDeclarationExpr variable,
 Expression iterable,
 Statement body)

ForEachStmt

public ForEachStmt(TokenRange tokenRange,
 VariableDeclarationExpr variable,
 Expression iterable,
 Statement body)

This constructor is used by the parser and is considered private.

ForEachStmt

public ForEachStmt(VariableDeclarationExpr variable,
 String iterable,
 BlockStmt body)

Method Details

accept

public <R,
A> R accept(GenericVisitor<R,A> v,
 A arg)

Description copied from interface: Visitable

Accept method for visitor support.

Specified by:

accept in interface Visitable

Type Parameters:

R - the type of the return value of the visitor

A - the type the user argument passed to the visitor

Parameters:

v - the visitor implementation

arg - the argument passed to the visitor (of type A)

Returns:

the result of the visit (of type R)

accept

public <A> void accept(VoidVisitor<A> v,
 A arg)

Description copied from interface: Visitable

Accept method for visitor support.

Specified by:

accept in interface Visitable

Type Parameters:

A - the type the argument passed for the visitor

Parameters:

v - the visitor implementation

arg - any value relevant for the visitor (of type A)

getBody

public Statement getBody()

Specified by:

getBody in interface NodeWithBody<ForEachStmt>

getIterable

public Expression getIterable()

getVariable

public VariableDeclarationExpr getVariable()

setBody

public ForEachStmt setBody(Statement body)

Specified by:

setBody in interface NodeWithBody<ForEachStmt>

setIterable

public ForEachStmt setIterable(Expression iterable)

setVariable

public ForEachStmt setVariable(VariableDeclarationExpr variable)

getVariableDeclarator

public VariableDeclarator getVariableDeclarator()

Convenience method that directly returns this foreach statement's single variable declarator. Note that any foreach statement's variable declaration expression (as returned by getVariable()) always has exactly one variable declarator.

Calling this method on a foreach statement forEachStmt is equivalent to calling forEachStmt.getVariable().getVariable(0).

Returns:

this foreach statement's single variable declarator.

hasFinalVariable

public boolean hasFinalVariable()

Convenience method that decides whether this foreach statement's variable is final. Note that any foreach statement's variable declaration expression (as returned by getVariable()) always has either no modifiers, or a single final modifier.

Calling this method on a foreach statement forEachStmt is equivalent to calling forEachStmt.getVariable().getModifiers().isNonEmpty() && forEachStmt.getVariable().getModifiers().get(0).getKeyword() == Modifier.Keyword.FINAL.

Returns:

true if this foreach statement's variable is final, and false otherwise.

clone

public ForEachStmt clone()

Overrides:

clone in class Statement

replace

public boolean replace(Node node,
 Node replacementNode)

Overrides:

replace in class Node

isForEachStmt

public boolean isForEachStmt()

Overrides:

isForEachStmt in class Statement

asForEachStmt

public ForEachStmt asForEachStmt()

Overrides:

asForEachStmt in class Statement

toForEachStmt

public Optional<ForEachStmt> toForEachStmt()

Overrides:

toForEachStmt in class Statement

ifForEachStmt

public void ifForEachStmt(Consumer<ForEachStmt> action)

Overrides:

ifForEachStmt in class Statement

getMetaModel

public ForEachStmtMetaModel getMetaModel()

Overrides:

getMetaModel in class Statement

Returns:

get JavaParser specific node introspection information.
