Method Details
-
getNameProperty
Returns the structural property descriptor for the "name" property of this node (child type:SimpleName
).- Returns:
- the property descriptor
- Since:
- 3.1
-
getExtraDimensionsProperty
Deprecated.In JLS8 and later, usegetExtraDimensions2Property()
instead.Returns the structural property descriptor for the "extraDimensions" property of this node (type:Integer
) (below JLS8 only).- Returns:
- the property descriptor
- Since:
- 3.1
-
getExtraDimensions2Property
Returns the structural property descriptor for the "extraDimensions" property of this node (element type:Dimension
) (added in JLS8 API).- Returns:
- the property descriptor
- Since:
- 3.10
-
getInitializerProperty
Returns structural property descriptor for the "initializer" property of this node (child type:Expression
).- Returns:
- the property descriptor
- Since:
- 3.1
-
getName
Returns the name of the variable declared in this variable declaration.- Returns:
- the variable name node
-
setName
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 int getExtraDimensions()Returns the number of extra array dimensions over and above the explicitly-specified type.For example,
int x[][]
has a type ofint
and two extra array dimensions;int[][] x
has a type ofint[][]
and zero extra array dimensions. The two constructs have different ASTs, even though there are really syntactic variants of the same variable declaration.In the JLS8 API, this method is a convenience method that counts
extraDimensions()
.- Returns:
- the number of extra array dimensions
- Since:
- 2.1
-
setExtraDimensions
public void setExtraDimensions(int dimensions) Deprecated.In the JLS8 API, this method is replaced byextraDimensions()
which contains a list ofDimension
nodes.Sets the number of extra array dimensions over and above the explicitly-specified type.For example,
int x[][]
has a type ofint
and two extra array dimensions;int[][] x
has a type ofint[][]
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 negativeUnsupportedOperationException
- if this operation is used in a JLS8 or later AST- Since:
- 2.1
-
extraDimensions
Returns the live ordered list of extra dimensions with optional annotations (added in JLS8 API).- Returns:
- the live list of extra dimensions with optional annotations (element type:
Dimension
) - Throws:
UnsupportedOperationException
- if this operation is used below JLS8- Since:
- 3.10
-
getInitializer
Returns the initializer of this variable declaration, ornull
if there is none.- Returns:
- the initializer expression node, or
null
if there is none
-
setInitializer
Sets or clears the initializer of this variable declaration.- Parameters:
initializer
- the initializer expression node, ornull
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
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
-
getExtraDimensions2Property()
instead.
