Field Detail

dimensions

protected final List<JavaExpression> dimensions

List of dimensions expressions. A {code null} element means that there is no dimension expression for the given array level.

initializers

protected final List<JavaExpression> initializers

List of initializers.

Constructor Detail

ArrayCreation

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

Creates an ArrayCreation object.

Parameters:

type - array type

dimensions - list of dimension expressions; a {code null} element means that there is no dimension expression for the given array level.

initializers - list of initializer expressions

Method Detail

getDimensions

public List<JavaExpression> getDimensions()

Returns a list representing the dimensions of this array creation. A {code null} element means that there is no dimension expression for the given array level.

Returns:

a list representing the dimensions of this array creation

getInitializers

public List<JavaExpression> getInitializers()

containsOfClass

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

Specified by:

containsOfClass in class JavaExpression

isDeterministic

public boolean isDeterministic(AnnotationProvider provider)

Description copied from class: JavaExpression

Returns true if the expression is deterministic.

Specified by:

isDeterministic in class JavaExpression

Parameters:

provider - an annotation provider (a type factory)

Returns:

true if this expression is deterministic

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 operations whose operands are all 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 je)

Description copied from class: JavaExpression

Returns true if and only if the two Java expressions are syntactically identical.

This exists for use by JavaExpression.containsSyntacticEqualJavaExpression(org.checkerframework.dataflow.expression.JavaExpression).

Specified by:

syntacticEquals in class JavaExpression

Parameters:

je - the other Java expression to compare to this one

Returns:

true if and only if the two Java expressions are syntactically identical

containsSyntacticEqualJavaExpression

public boolean containsSyntacticEqualJavaExpression(JavaExpression other)

Description copied from class: JavaExpression

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

Specified by:

containsSyntacticEqualJavaExpression in class JavaExpression

Parameters:

other - the JavaExpression to search for

Returns:

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

toString

public String toString()

Overrides:

toString in class Object

toStringDebug

public String toStringDebug()

Description copied from class: JavaExpression

Format this verbosely, for debugging.

Overrides:

toStringDebug in class JavaExpression

Returns:

a verbose string representation of this

accept

public <R,P> R accept(JavaExpressionVisitor<R,P> visitor,
                      P p)

Description copied from class: JavaExpression

Accept method of the visitor pattern.

Specified by:

accept in class JavaExpression

Type Parameters:

R - result type of the operation

P - parameter type

Parameters:

visitor - the visitor to be applied to this JavaExpression

p - the parameter for this operation

Returns:

the result of visiting this
