Detailed Description

This class provides services to compare sets of information. The use of this tool can works after a copy, acted by a CopyTool.

• Compare(...) compares two DataSet and returns the result.
• SourceUnbound(...) builds the difference between a relocation dictionary and a source set of information.
• TargetUnbound(...) does the same between a relocation dictionary and a target set of information.
• Cut(aDataSet, anLabel) removes a set of attributes.
• IsSelfContained(...) returns true if all the labels of the attributes of the given DataSet are descendant of the given label.

Member Function Documentation

Compare()

static void TDF_ComparisonTool::Compare ( const Handle< TDF_DataSet > &  aSourceDataSet, const Handle< TDF_DataSet > &  aTargetDataSet, const TDF_IDFilter &  aFilter, const Handle< TDF_RelocationTable > &  aRelocationTable  )

static

Compares <aSourceDataSet> with <aTargetDataSet>, updating <aRelocationTable> with labels and attributes found in both sets.

Cut()

static void TDF_ComparisonTool::Cut ( const Handle< TDF_DataSet > &  aDataSet )

static

Removes attributes from <aDataSet>.

IsSelfContained()

static Standard_Boolean TDF_ComparisonTool::IsSelfContained ( const TDF_Label &  aLabel, const Handle< TDF_DataSet > &  aDataSet  )

static

Returns true if all the labels of <aDataSet> are descendant of <aLabel>.

SourceUnbound()

static Standard_Boolean TDF_ComparisonTool::SourceUnbound ( const Handle< TDF_DataSet > &  aRefDataSet, const Handle< TDF_RelocationTable > &  aRelocationTable, const TDF_IDFilter &  aFilter, const Handle< TDF_DataSet > &  aDiffDataSet, const Standard_Integer  anOption = 2  )

static

Finds from <aRefDataSet> all the keys not bound into <aRelocationTable> and put them into <aDiffDataSet>. Returns True if the difference contains at least one key. (A key is a source object).

<anOption> may take the following values: 1 : labels treatment only; 2 : attributes treatment only (default value); 3 : both labels & attributes treatment.

TargetUnbound()

static Standard_Boolean TDF_ComparisonTool::TargetUnbound ( const Handle< TDF_DataSet > &  aRefDataSet, const Handle< TDF_RelocationTable > &  aRelocationTable, const TDF_IDFilter &  aFilter, const Handle< TDF_DataSet > &  aDiffDataSet, const Standard_Integer  anOption = 2  )

static

Substracts from <aRefDataSet> all the items bound into <aRelocationTable>. The result is put into <aDiffDataSet>. Returns True if the difference contains at least one item. (An item is a target object).

<anOption> may take the following values: 1 : labels treatment only; 2 : attributes treatment only(default value); 3 : both labels & attributes treatment.
