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 Method 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 JDBCDynamicQLQueryMetaData against the specified object. Returns true if the objects are the same. Two JDBCDynamicQLQueryMetaData are the same if they are both invoked by the same method.

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 JDBCDynamicQLQueryMetaData. The hashcode is computed by the method which invokes this query.

Returns:
a hash code value for this object

toString

public String toString()
Returns a string describing this JDBCDynamicQLQueryMetaData. The exact details of the representation are unspecified and subject to change, but the following may be regarded as typical:

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

Returns:
a string representation of the object
