Method Detail
-
numericalValue
@Deprecated default Long numericalValue()
Deprecated.Use numberValue() instead.Returns the value as a Long number, ornull
if it is not possible.
-
numberValue
Number numberValue()
Returns the value as a number, ornull
if it is not possible.- Since:
- 6.2
-
numberOfSubValues
int numberOfSubValues()
If this value consists of sub-values, returns the number of these sub-values. Otherwise returns 1.- Restriction:
- This method is not intended to be referenced by clients.
-
getSubValue
org.eclipse.cdt.internal.core.dom.parser.cpp.ICPPEvaluation getSubValue(int index)
If this value consists of sub-values, returns the sub-value at the given index. Otherwise, returns this value (represented as an ICPPEvaluation) if the index 0 is passed. EvalFixed.INCOMPLETE is returned if the given index is out of bounds.- Restriction:
- This method is not intended to be referenced by clients.
-
getAllSubValues
org.eclipse.cdt.internal.core.dom.parser.cpp.ICPPEvaluation[] getAllSubValues()
If this value consists of sub-values, returns an array containing all of them. Otherwise, returns an array containing 1 element representing this value. Not all implementations implement this; some may returnnull
.- Restriction:
- This method is not intended to be referenced by clients.
-
getEvaluation
org.eclipse.cdt.internal.core.dom.parser.cpp.ICPPEvaluation getEvaluation()
Returns the evaluation object if this value cannot be represented as a single numerical value, ornull
otherwise. This can happen if the value is dependent, or it's a composite value. IfnumberValue()
returnsnull
,getEvaluation()
returns notnull
and vice versa.- Restriction:
- This method is not intended to be referenced by clients.
-
getSignature
char[] getSignature()
Returns a signature uniquely identifying the value. Two values with identical signatures are guaranteed to be equal.
-
getInternalExpression
@Deprecated default char[] getInternalExpression()
Deprecated.Returns an empty character array.- Restriction:
- This method is not intended to be referenced by clients.
-
getUnknownBindings
@Deprecated default IBinding[] getUnknownBindings()
Deprecated.Returns an empty array.- Restriction:
- This method is not intended to be referenced by clients.
-
setSubValue
void setSubValue(int position, org.eclipse.cdt.internal.core.dom.parser.cpp.ICPPEvaluation newValue)
If this value consists of sub-values, set the sub-value at the given position to the given new value. Otherwise, set this value to the given new value. Not all implementations implement this; for some, a call to this may have no effect.- Restriction:
- This method is not intended to be referenced by clients.
-
clone
IValue clone()
Make a deep copy of this value.- Since:
- 6.2
-
marshal
void marshal(org.eclipse.cdt.internal.core.dom.parser.ITypeMarshalBuffer buffer) throws org.eclipse.core.runtime.CoreException
Serialize this value to the given type marshal buffer.- Throws:
org.eclipse.core.runtime.CoreException
- Restriction:
- This method is not intended to be referenced by clients.
-
isEquivalentTo
boolean isEquivalentTo(IValue other)
Returns true if this value is equivalent to 'other' for declaration matching purposes.- Restriction:
- This method is not intended to be referenced by clients.
