Method Detail

setFieldTask

public void setFieldTask(AnalysisField field,
                         AnalysisFuture<JavaConstant> task)

Record the task computing the field value. It will be retrieved and executed when the field is marked as read.

setFieldValue

public void setFieldValue(AnalysisField field,
                          JavaConstant value)

Record the field value produced by the task set in TypeData.setFieldTask(AnalysisField, AnalysisFuture), i.e., the snapshot, already transformed and replaced.

getFieldValue

public Object getFieldValue(AnalysisField field)

Return a task for transforming and snapshotting the field value, effectively a future for ImageHeapScanner.createFieldValue(AnalysisField, ValueSupplier, ObjectScanner.ScanReason), or its result, a JavaConstant.

readFieldValue

public JavaConstant readFieldValue(AnalysisField field)

Returns the field value, i.e., a JavaConstant. If the value is not yet materialized then the future is executed on the current thread.
