Method Detail

getExtraDimensionsProperty

public final 
SimplePropertyDescriptor getExtraDimensionsProperty()
Returns structural property descriptor for the "extraDimensions" property of this node.

Returns:
the property descriptor
Since:
3.1

getInitializerProperty

public final 
ChildPropertyDescriptor getInitializerProperty()
Returns structural property descriptor for the "initializer" property of this node.

Returns:
the property descriptor
Since:
3.1

getNameProperty

public final 
ChildPropertyDescriptor getNameProperty()
Returns structural property descriptor for the "name" property of this node.

Returns:
the property descriptor
Since:
3.1

getName

public abstract 
SimpleName getName()
Returns the name of the variable declared in this variable declaration.

Returns:
the variable name node

setName

public abstract void setName(
SimpleName variableName)
Sets the name of the variable declared in this variable declaration to the given name.

Parameters:
variableName - the new variable name
Throws:
IllegalArgumentException - if:
  • the node belongs to a different AST
  • the node already has a parent

getExtraDimensions

public abstract int getExtraDimensions()
Returns the number of extra array dimensions over and above the explicitly-specified type.

For example, int x[][] has a type of int and two extra array dimensions; int[][] x has a type of int[][] and zero extra array dimensions. The two constructs have different ASTs, even though there are really syntactic variants of the same variable declaration.

Returns:
the number of extra array dimensions
Since:
2.1

setExtraDimensions

public abstract void setExtraDimensions(int dimensions)
Sets the number of extra array dimensions over and above the explicitly-specified type.

For example, int x[][] has a type of int and two extra array dimensions; int[][] x has a type of int[][] and zero extra array dimensions. The two constructs have different ASTs, even though there are really syntactic variants of the same variable declaration.

Parameters:
dimensions - the number of array dimensions
Throws:
IllegalArgumentException - if the number of dimensions is negative
Since:
2.1

getInitializer

public abstract 
Expression getInitializer()
Returns the initializer of this variable declaration, or null if there is none.

Returns:
the initializer expression node, or null if there is none

setInitializer

public abstract void setInitializer(
Expression initializer)
Sets or clears the initializer of this variable declaration.

Parameters:
initializer - the initializer expression node, or null if there is none
Throws:
IllegalArgumentException - if:
  • the node belongs to a different AST
  • the node already has a parent
  • a cycle in would be created

resolveBinding

public 
IVariableBinding resolveBinding()
Resolves and returns the binding for the variable declared in this variable declaration.

Note that bindings are generally unavailable unless requested when the AST is being built.

Returns:
the binding, or null if the binding cannot be resolved
