List of dimensions expressions. {code null} means that there is no dimension expression.

initializers

protected final List<JavaExpression> initializers

List of initializers.

Constructor Detail

ArrayCreation

public ArrayCreation(TypeMirror type,
                     List<? extends JavaExpression> dimensions,
                     List<JavaExpression> initializers)

Creates an ArrayCreation object.

Parameters:

type - array type

dimensions - list of dimension expressions; {code null} means that there is no dimension expression

initializers - list of initializer expressions

Method Detail

getDimensions

public List<? extends JavaExpression> getDimensions()

Returns a list of receivers representing the dimension of this array creation.

Returns:

a list of receivers representing the dimension of this array creation

getInitializers

public List<JavaExpression> getInitializers()

containsOfClass

public boolean containsOfClass(Class<? extends JavaExpression> clazz)

Specified by:

containsOfClass in class JavaExpression

isUnassignableByOtherCode

public boolean isUnassignableByOtherCode()

Description copied from class: JavaExpression

Returns true if and only if the value this expression stands for cannot be changed (with respect to ==) by a method call. This is the case for local variables, the self reference, final field accesses whose receiver is JavaExpression.isUnassignableByOtherCode(), and binary operations whose left and right operands are both JavaExpression.isUnmodifiableByOtherCode().

Specified by:

isUnassignableByOtherCode in class JavaExpression

See Also:

JavaExpression.isUnmodifiableByOtherCode()

isUnmodifiableByOtherCode

public boolean isUnmodifiableByOtherCode()

Description copied from class: JavaExpression

Returns true if and only if the value this expression stands for cannot be changed by a method call, including changes to any of its fields.

Approximately, this returns true if the expression is JavaExpression.isUnassignableByOtherCode() and its type is immutable.

Specified by:

isUnmodifiableByOtherCode in class JavaExpression

See Also:

JavaExpression.isUnassignableByOtherCode()

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(@Nullable Object obj)

Overrides:

equals in class Object

syntacticEquals

public boolean syntacticEquals(JavaExpression other)

Description copied from class: JavaExpression

Returns true if and only if the two receivers are syntactically identical.

Overrides:

syntacticEquals in class JavaExpression

Parameters:

other - the other object to compare to this one

Returns:

true if and only if the two receivers are syntactically identical

containsSyntacticEqualJavaExpression

public boolean containsSyntacticEqualJavaExpression(JavaExpression other)

Description copied from class: JavaExpression

Returns true if and only if this receiver contains a receiver that is syntactically equal to other.

Overrides:

containsSyntacticEqualJavaExpression in class JavaExpression

Returns:

true if and only if this receiver contains a receiver that is syntactically equal to other

toString

public String toString()

Overrides:

toString in class Object
