  com.cmpware.elf.VariableType
      com.cmpware.elf.ScalarType

All Implemented Interfaces:

TreeViewable

public class ScalarType
extends VariableType

This class stores all the data necessary for a DWARF Scalar variable type. This is the final entry in a type tree and is used to produce the final address and value of the variable.

Method Detail

getScalarType

public static ScalarType getScalarType(VariableType parent,
                                       Variable variable,
                                       Tag typeTag)

This method returns a Scalar Type with data filled in from the ELF /DWARF tag. Note that this tag should be a DW_TAG_base_type.

Parameters:

parent - the variable parent.

variable - the variable.

typeTag - The ELF /DWARF tag type.

Returns:

This method returns a Scalar type with all of the fields filled in according to the input DWARF tag.

getValue

public void getValue()

This method returns the value of the scalar type. This is done by reading the proper address in the current processor. The local variables addr and val are set by this method.

Description copied from interface: TreeViewable

This method returns the parent of this object.

Returns:

This method returns the parent of this object.

hasChildren

public boolean hasChildren()

Description copied from interface: TreeViewable

This method returns true if this object has children and false otherwise.

Returns:

This method returns true if this object has children and false otherwise.

getText

public java.lang.String getText()

Description copied from interface: TreeViewable

This method returns the text string associated with this object.

Returns:

This method returns the text string associated with this object.

getImage

public org.eclipse.swt.graphics.Image getImage()

Description copied from interface: TreeViewable

This method returns an image used as a decorator.

Returns:

This method returns an image used as a decorator.

toString

public java.lang.String toString(boolean byteSwap)

This method returns a string representation of the variable type data.

Overrides:

toString in class VariableType

Parameters:

byteSwap - the byte swappting flag from the ELF file.

Returns:

This method returns a string representation of the variable type data.
