Package ghidra.app.cmd.data

Class CreateDataCmd

java.lang.Object

ghidra.app.cmd.data.CreateDataCmd

All Implemented Interfaces:

Command

public class CreateDataCmd
extends java.lang.Object
implements Command

This command will create a data of type dataType at the given address. This command will only work for fixed length dataTypes. If there are any existing instructions in the area to be made into data, the command will fail. Existing data in the area may be replaced with the new dataType (with optional pointer conversion). If the existing dataType is a pointer, then the existing data will be changed into a pointer to the given dataType. If the given dataType is a default-pointer, it will become a pointer to the existing type.

Constructor Summary

Constructors

Constructor	Description
CreateDataCmd(Address addr, boolean force, boolean stackPointers, DataType dataType)	This is the same as CreateDataCmd(Address, boolean, DataType) except that it allows the caller to control whether or not pointer conversion should be handled.
CreateDataCmd(Address addr, boolean force, DataType dataType)	Constructs a command for creating data at an address.
CreateDataCmd(Address addr, DataType dataType)	Constructs a command for creating data at an address.
CreateDataCmd(Address addr, DataType dataType, boolean isCycle, boolean stackPointers)	This is the same as CreateDataCmd(Address, DataType) except that it allows the caller to control whether or not pointer conversion should be handled.
CreateDataCmd(Address addr, DataType dataType, boolean stackPointers, DataUtilities.ClearDataMode clearMode)	This constructor provides the most flexibility when creating data, allowing optional pointer conversion and various clearing options for conflicting data.

Method Summary

Modifier and Type	Method	Description
boolean	applyTo(DomainObject obj)	Applies the command to the given domain object.

Constructor Detail

CreateDataCmd

public CreateDataCmd(Address addr,
                     boolean force,
                     DataType dataType)

Constructs a command for creating data at an address. Simple pointer conversion will NOT be performed.

Parameters:

addr - the address at which to apply the datatype. Offcut data address allowed, provided force==true.

force - if true any existing conflicting data will be cleared

dataType - the datatype to be applied at the given address.

CreateDataCmd

public CreateDataCmd(Address addr,
                     boolean force,
                     boolean stackPointers,
                     DataType dataType)

This is the same as CreateDataCmd(Address, boolean, DataType) except that it allows the caller to control whether or not pointer conversion should be handled.

Parameters:

addr - the address at which to apply the datatype. Offcut data address allowed, provided force==true.

force - if true any existing conflicting data will be cleared

stackPointers - if true simple pointer conversion is enabled (see DataUtilities.reconcileAppliedDataType(DataType, DataType, boolean)).

dataType - the datatype to be applied at the given address.

CreateDataCmd

public CreateDataCmd(Address addr,
                     DataType dataType)

Constructs a command for creating data at an address. Simple pointer conversion will NOT be performed and existing data will not be cleared.

Parameters:

addr - the address at which to apply the datatype.

dataType - the datatype to be applied at the given address.

CreateDataCmd

public CreateDataCmd(Address addr,
                     DataType dataType,
                     boolean isCycle,
                     boolean stackPointers)

This is the same as CreateDataCmd(Address, DataType) except that it allows the caller to control whether or not pointer conversion should be handled.

Parameters:

addr - the address at which to apply the datatype.

dataType - the datatype to be applied at the given address.

isCycle - true indicates this is from a cycle group action.

stackPointers - if true simple pointer conversion is enabled (see DataUtilities.reconcileAppliedDataType(DataType, DataType, boolean)).

CreateDataCmd

public CreateDataCmd(Address addr,
                     DataType dataType,
                     boolean stackPointers,
                     DataUtilities.ClearDataMode clearMode)

This constructor provides the most flexibility when creating data, allowing optional pointer conversion and various clearing options for conflicting data.

Parameters:

addr - the address at which to apply the datatype.

dataType - the datatype to be applied at the given address.

stackPointers - if true simple pointer conversion is enabled (see DataUtilities.reconcileAppliedDataType(DataType, DataType, boolean)).

clearMode - indicates how conflicting data should be cleared
