Method Detail

isAllowedParentBuilder

public boolean isAllowedParentBuilder(MMObjectBuilder builder)

Deprecated.

Returns whether this database support layer allows for buidler to be a parent builder (that is, other builders can 'extend' this builder and its database tables).

Parameters:

builder - the builder to test

Returns:

true if the builder can be extended

Since:

MMBase-1.6

registerParentBuilder

public void registerParentBuilder(MMObjectBuilder parent,
                                  MMObjectBuilder child)
                           throws StorageException

Deprecated.

Registers a builder as a parent builder (that is, other buidlers can 'extend' this builder and its database tables). At the least, this code should check whether the builder is allowed as a parent builder, and throw an exception if this is not possible. This method can be overridden to allow for optimization of code regarding such builders.

Parameters:

parent - the parent builder to register

child - the builder to register as the parent's child

Throws:

UnsupportedDatabaseOperationException - when the databse layer does not allow extension of this builder

StorageException

Since:

MMBase-1.6

decodeDBnodeField

public MMObjectNode decodeDBnodeField(MMObjectNode node,
                                      java.lang.String fieldName,
                                      java.sql.ResultSet resultSet,
                                      int i)

Deprecated.

Sets the value of the field with name 'fieldName' in the node. Using the given database result set. The value of the field will be taken from the i-th collumn of the result set. Note: This method may attempt to map the provided 'database' fieldname to the MMBase name. In very specific cases, this may not have the desired result.

Parameters:

node - The node from which a field must be set

fieldName - The name of the field which must be set. This is expected to be the field as used by the database, not the field as used by MMBase.

resultSet - The resultset from which the value of the field must be obtained

i - The integer indicating from which position the value must be gotten from the resultSet record.

decodeDBnodeField

public MMObjectNode decodeDBnodeField(MMObjectNode node,
                                      java.lang.String fieldName,
                                      java.sql.ResultSet resultSet,
                                      int i,
                                      java.lang.String prefix)

Deprecated.

Parameters:

prefix - When using cluster nodes, the key of the value map of the node must be prefixed (e.g. with 'news.')

decodeDBnodeField(MMObjectNode, String, ResultSet, int)

getMMNodeSearch2SQL

public java.lang.String getMMNodeSearch2SQL(java.lang.String where,
                                            MMObjectBuilder bul)

Deprecated.

Converts an MMNODE expression to an SQL expression. Returns the result as an SQL where-clause, but with the leading "WHERE " left out.

Parameters:

where - The MMNODE expression.

bul - The builder for the type of nodes that is queried.

Returns:

The SQL expression.
