Method Summary

Modifier and Type	Method and Description
boolean	nullPlusNonNullIsNull() ModeShape uses arithmetic operations in criteria, and in the current implementation if one operand is null then the operations returns the other.
boolean	nullsAreSortedAtEnd() Assumed to be false for JCR implementations (meaning that sort order IS used), though section 6.7.37 of JCR 2.0 specification says ordering of null values is implementation-determined.
boolean	nullsAreSortedAtStart() Assumed to be false for JCR implementations (meaning that sort order IS used), though section 6.7.37 of JCR 2.0 specification says ordering of null values is implementation-determined.
boolean	nullsAreSortedHigh() Assumed to be false for JCR implementations, though section 6.7.37 of JCR 2.0 specification says ordering of null values is implementation-determined.
boolean	nullsAreSortedLow() Assumed to be true for JCR implementations, though section 6.7.37 of JCR 2.0 specification says ordering of null values is implementation-determined.
boolean	supportsFullOuterJoins() ModeShape does support FULL OUTER JOIN, so this method returns true when this driver connects to a ModeShape JCR repository.
boolean	supportsUnion() ModeShape does support UNION, so this method returns true when this driver connects to a ModeShape JCR repository.
boolean	supportsUnionAll() ModeShape does support UNION ALL, so this method returns true when this driver connects to a ModeShape JCR repository.

Constructor Detail

ModeShapeMetaData

public ModeShapeMetaData(JcrConnection connection)

Method Detail

supportsFullOuterJoins

public boolean supportsFullOuterJoins()

ModeShape does support FULL OUTER JOIN, so this method returns true when this driver connects to a ModeShape JCR repository.

Specified by:

supportsFullOuterJoins in interface DatabaseMetaData

Overrides:

supportsFullOuterJoins in class JcrMetaData

See Also:

DatabaseMetaData.supportsFullOuterJoins()

supportsUnion

public boolean supportsUnion()

ModeShape does support UNION, so this method returns true when this driver connects to a ModeShape JCR repository.

Specified by:

supportsUnion in interface DatabaseMetaData

Overrides:

supportsUnion in class JcrMetaData

See Also:

DatabaseMetaData.supportsUnion()

supportsUnionAll

public boolean supportsUnionAll()

ModeShape does support UNION ALL, so this method returns true when this driver connects to a ModeShape JCR repository.

Specified by:

supportsUnionAll in interface DatabaseMetaData

Overrides:

supportsUnionAll in class JcrMetaData

See Also:

DatabaseMetaData.supportsUnionAll()

nullPlusNonNullIsNull

public boolean nullPlusNonNullIsNull()

ModeShape uses arithmetic operations in criteria, and in the current implementation if one operand is null then the operations returns the other. Therefore, 'null + X = X', so this method returns false.

Specified by:

nullPlusNonNullIsNull in interface DatabaseMetaData

Overrides:

nullPlusNonNullIsNull in class JcrMetaData

See Also:

DatabaseMetaData.nullPlusNonNullIsNull()

nullsAreSortedAtEnd

public boolean nullsAreSortedAtEnd()

Assumed to be false for JCR implementations (meaning that sort order IS used), though section 6.7.37 of JCR 2.0 specification says ordering of null values is implementation-determined.

ModeShape definitely uses sort order. Therefore, this method always returns false.

Specified by:

nullsAreSortedAtEnd in interface DatabaseMetaData

Overrides:

nullsAreSortedAtEnd in class JcrMetaData

See Also:

DatabaseMetaData.nullsAreSortedAtEnd()

nullsAreSortedAtStart

public boolean nullsAreSortedAtStart()

Assumed to be false for JCR implementations (meaning that sort order IS used), though section 6.7.37 of JCR 2.0 specification says ordering of null values is implementation-determined.

ModeShape definitely uses sort order. Therefore, this method always returns false.

Specified by:

nullsAreSortedAtStart in interface DatabaseMetaData

Overrides:

nullsAreSortedAtStart in class JcrMetaData

See Also:

DatabaseMetaData.nullsAreSortedAtStart()

nullsAreSortedHigh

public boolean nullsAreSortedHigh()

Assumed to be false for JCR implementations, though section 6.7.37 of JCR 2.0 specification says ordering of null values is implementation-determined.

ModeShape sorts null values to be lower than non-null values. Therefore, this method returns false.

Specified by:

nullsAreSortedHigh in interface DatabaseMetaData

Overrides:

nullsAreSortedHigh in class JcrMetaData

See Also:

DatabaseMetaData.nullsAreSortedHigh()

nullsAreSortedLow

public boolean nullsAreSortedLow()

Assumed to be true for JCR implementations, though section 6.7.37 of JCR 2.0 specification says ordering of null values is implementation-determined.

ModeShape sorts null values to be lower than non-null values. Therefore, this method returns true.

Specified by:

nullsAreSortedLow in interface DatabaseMetaData

Overrides:

nullsAreSortedLow in class JcrMetaData

See Also:

DatabaseMetaData.nullsAreSortedLow()
