Method Details

getSignature

String getSignature()
             throws DebugException

Returns the JNI-style signature for the type of this value, or null if the value is null.

Returns:

signature, or null if signature is null

Throws:

DebugException - if this method fails. Reasons include:

• Failure communicating with the VM. The DebugException's status code contains the underlying exception responsible for the failure.
• The type associated with the signature is not yet loaded

getGenericSignature

String getGenericSignature()
                    throws DebugException

Returns the generic signature as defined in the JVM specification for the type of this value. Returns null if the value is null, or if the type of this value is not a generic type.

Returns:

signature, or null if generic signature not available

Throws:

DebugException - if this method fails. Reasons include:

• Failure communicating with the VM. The DebugException's status code contains the underlying exception responsible for the failure.
• The type associated with the signature is not yet loaded

Since:

3.1

getJavaType

IJavaType getJavaType()
               throws DebugException

Returns the type of this value, or null if this value represents the null value

Returns:

the type of this value, or null if this value represents the null value

Throws:

DebugException - if the request fails

Since:

2.0

isNull

boolean isNull()

Returns whether this value represents null.

Returns:

whether this value represents null
