Constructor Detail

JDBCAutomaticQueryMetaData

public JDBCAutomaticQueryMetaData(Method method,
                          JDBCReadAheadMetaData readAhead,
                          Class qlCompiler,
                          boolean lazyResultSetLoading)

Constructs a JDBCAutomaticQueryMetaData which is invoked by the specified method.

Parameters:

method - the method which invokes this query

Method Detail

getMethod

public Method getMethod()

Description copied from interface: JDBCQueryMetaData

Gets the method which invokes this query.

Specified by:

getMethod in interface JDBCQueryMetaData

Returns:

the NamedMethodMetaData representing the method on the object which invokes this query

isResultTypeMappingLocal

public boolean isResultTypeMappingLocal()

Description copied from interface: JDBCQueryMetaData

Is the result set of ejbSelect is mapped to local ejb objects or remote ejb objects.

Specified by:

isResultTypeMappingLocal in interface JDBCQueryMetaData

Returns:

true, if the result set is to be local objects

getReadAhead

public JDBCReadAheadMetaData getReadAhead()

Gets the read ahead metadata for the query.

Specified by:

getReadAhead in interface JDBCQueryMetaData

Returns:

the read ahead metadata for the query.

getQLCompilerClass

public Class getQLCompilerClass()

Specified by:

getQLCompilerClass in interface JDBCQueryMetaData

Returns:

EJBQL compiler implementation

isLazyResultSetLoading

public boolean isLazyResultSetLoading()

Specified by:

isLazyResultSetLoading in interface JDBCQueryMetaData

equals

public boolean equals(Object o)

Compares this JDBCAutomaticQueryMetaData against the specified object. Returns true if the objects are the same. Two JDBCAutomaticQueryMetaData are the same if they are both invoked by the same method.

Overrides:

equals in class Object

Parameters:

o - the reference object with which to compare

Returns:

true if this object is the same as the object argument; false otherwise

hashCode

public int hashCode()

Returns a hashcode for this JDBCAutomaticQueryMetaData. The hashcode is computed by the method which invokes this query.

Overrides:

hashCode in class Object

Returns:

a hash code value for this object

toString

public String toString()

Returns a string describing this JDBCAutomaticQueryMetaData. The exact details of the representation are unspecified and subject to change, but the following may be regarded as typical:

"[JDBCAutomaticQueryMetaData: method=public org.foo.User findByName(java.lang.String)]"

Overrides:

toString in class Object

Returns:

a string representation of the object
