Method Detail
-
isFlexibleArrayComponent
public boolean isFlexibleArrayComponent()
Description copied from interface:DataTypeComponentDetermine if this component corresponds to a unsized flexible array which is permitted as the trailing component within a structure.- Specified by:
isFlexibleArrayComponentin interfaceDataTypeComponent- Returns:
- true if component is a trailing flexible array component.
-
getOffset
public int getOffset()
Description copied from interface:DataTypeComponentGet the byte offset of where this component begins relative to the start of the parent data type.NOTE: The special case of a structure flexible array component returns an offset equal to the length of the parent structure since the flexible array component is not included in a structure's length.
- Specified by:
getOffsetin interfaceDataTypeComponent- Returns:
- offset of start of component relative to the start of the parent data type.
-
getEndOffset
public int getEndOffset()
Description copied from interface:DataTypeComponentGet the byte offset of where this component ends relative to the start of the parent data type.NOTE: The special case of a structure flexible array component returns -1 since its length is undefined.
- Specified by:
getEndOffsetin interfaceDataTypeComponent- Returns:
- offset of end of component relative to the start of the parent data type.
-
getComment
public java.lang.String getComment()
Description copied from interface:DataTypeComponentGet the comment for this dataTypeComponent.- Specified by:
getCommentin interfaceDataTypeComponent
-
setComment
public void setComment(java.lang.String comment)
Description copied from interface:DataTypeComponentSets the comment for the component.- Specified by:
setCommentin interfaceDataTypeComponent- Parameters:
comment- this components comment.
-
getFieldName
public java.lang.String getFieldName()
Description copied from interface:DataTypeComponentGet the name of the field name as a component of a Data Type.- Specified by:
getFieldNamein interfaceDataTypeComponent- Returns:
- the name as a component of another Data Type.
-
getDefaultFieldName
public java.lang.String getDefaultFieldName()
Description copied from interface:DataTypeComponentReturns a default Field name. Used only if a field name is not set.- Specified by:
getDefaultFieldNamein interfaceDataTypeComponent
-
setFieldName
public void setFieldName(java.lang.String name) throws DuplicateNameExceptionDescription copied from interface:DataTypeComponentSets the field name. If the field name is empty it will be set to null, which is the default field name. An exception is thrown if one of the parent's other components already has the specified field name.- Specified by:
setFieldNamein interfaceDataTypeComponent- Parameters:
name- the new field name for this component.- Throws:
DuplicateNameException- if another component of the parent has the specified field name.
-
checkDefaultFieldName
public static void checkDefaultFieldName(java.lang.String fieldName) throws DuplicateNameException- Throws:
DuplicateNameException
-
getDataType
public DataType getDataType()
Description copied from interface:DataTypeComponentReturns the dataType in this component.NOTE: If this component corresponds to a structure flexible array the returned data type reflects the base type of the array (e.g., char is returned for a flexible char array).
- Specified by:
getDataTypein interfaceDataTypeComponent- Returns:
- the dataType in this component
-
getParent
public DataType getParent()
Description copied from interface:DataTypeComponentreturns the dataType that contains this component.- Specified by:
getParentin interfaceDataTypeComponent- Returns:
- the dataType that contains this component.
-
getLength
public int getLength()
Description copied from interface:DataTypeComponentGet the length of this component.NOTE: The special case of a structure flexible array component returns 0 since its length is undefined.
- Specified by:
getLengthin interfaceDataTypeComponent- Returns:
- the length of this component or 0 for a structure flexible array.
-
getOrdinal
public int getOrdinal()
Description copied from interface:DataTypeComponentGet the ordinal position within the parent dataType.NOTE: The special case of a structure flexible array component returns an ordinal equal to the parent structure's
Structure.getNumComponents()since it is not included in the list of normal components (seeStructure.getFlexibleArrayComponent().- Specified by:
getOrdinalin interfaceDataTypeComponent- Returns:
- ordinal of this component within the parent data type.
-
getDefaultSettings
public Settings getDefaultSettings()
Description copied from interface:DataTypeComponentGets the default settings for this data type component.- Specified by:
getDefaultSettingsin interfaceDataTypeComponent- Returns:
- a Settings object that is the set of default values for this dataType component
-
setDefaultSettings
public void setDefaultSettings(Settings settings)
Description copied from interface:DataTypeComponentSet default settings for this dataType.- Specified by:
setDefaultSettingsin interfaceDataTypeComponent- Parameters:
settings- the new default settings.
-
hashCode
public int hashCode()
- Overrides:
hashCodein classjava.lang.Object
-
equals
public boolean equals(java.lang.Object obj)
- Overrides:
equalsin classjava.lang.Object
-
isEquivalent
public boolean isEquivalent(DataTypeComponent dtc)
Description copied from interface:DataTypeComponentReturns true if the given dataTypeComponent is equivalent to this dataTypeComponent. A dataTypeComponent is "equivalent" if the other component has a data type that is equivalent to this component's data type. The dataTypeComponents must also have the same offset, length, ordinal, field name, and comment.- Specified by:
isEquivalentin interfaceDataTypeComponent- Parameters:
dtc- the dataTypeComponent being tested for equivalence.- Returns:
- true if the given dataTypeComponent is equivalent to this dataTypeComponent.
