Method Detail

getColumnName

public java.lang.String getColumnName()

Description copied from interface: IMethodMapping

Returns the database table column name this method method is method to.

Specified by:

getColumnName in interface IMethodMapping

Returns:

The database table column name this method method is method to.

setColumnName

public void setColumnName(java.lang.String fieldName)

Description copied from interface: IMethodMapping

Sets the database column name this method method is method to.

Specified by:

setColumnName in interface IMethodMapping

Parameters:

fieldName - The column name to map to.

getColumnType

public int getColumnType()

Description copied from interface: IMethodMapping

Returns the column type as defined in the database. The int returned will match one of the java.sql.Types.XXX constants.

Specified by:

getColumnType in interface IMethodMapping

Returns:

The column type as defined in the database.

setColumnType

public void setColumnType(int columnType)

Description copied from interface: IMethodMapping

Sets the column type as defined in the database. The int should match one of the java.sql.Types.XXX constants.

Specified by:

setColumnType in interface IMethodMapping

Parameters:

columnType - The column type as defined in the database.

isNumberType

protected boolean isNumberType()

isStringType

protected boolean isStringType()

getObjectMethod

public java.lang.reflect.Method getObjectMethod()

Description copied from interface: IMethodMapping

Returns the method instance this method method is method from.

Specified by:

getObjectMethod in interface IMethodMapping

Returns:

The Method instance this method method is method from.

setObjectMethod

public void setObjectMethod(java.lang.reflect.Method member)

Description copied from interface: IMethodMapping

The method instance this method method maps from.

Specified by:

setObjectMethod in interface IMethodMapping

Parameters:

member - The Method instance this method method maps from.

isPrimaryKey

public boolean isPrimaryKey()

Description copied from interface: IMethodMapping

Returns true if the database column referenced by this method method is the primary key of the table it comes from.

Specified by:

isPrimaryKey in interface IMethodMapping

Returns:

True if the database column referenced by this method method is the primary key of the table it comes from. False if not.

setPrimaryKey

public void setPrimaryKey(boolean isPrimaryKey)

Description copied from interface: IMethodMapping

Sets whether or not the column referenced by this method method is the primary key.

Specified by:

setPrimaryKey in interface IMethodMapping

Parameters:

isPrimaryKey - Set to true if the column referenced by this method method is the primary key of the table it comes from.

isTableMapped

public boolean isTableMapped()

Description copied from interface: IMethodMapping

Returns true if the database column referenced by this method method exists in a table in the database. False if not.
