containsOfClass

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

Specified by:

containsOfClass in class JavaExpression

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 containsSyntacticEqualJavaExpression.

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

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

JavaExpression.isUnassignableByOtherCode()
