Example 1 with ValueConverter

use of org.apache.sis.xml.ValueConverter in project sis by apache.

the class ModifiableIdentifierMap method put.

/**
 * Sets the code of the identifier having the given authority to the given value.
 * If no identifier is found for the given authority, a new one is created.
 * If more than one identifier is found for the given authority, then all previous identifiers may be removed
 * in order to ensure that the new entry will be the first entry, so it can be find by the {@code get} method.
 *
 * <p>If the given {@code authority} is {@code HREF} and if the given string is parsable as a {@link URI},
 * then this method will actually store the value as the {@link XLink#getHRef()} property of the {@code XLink}
 * associated to the {@code XLINK} key. Only if the given string can not be parsed, then the value is stored
 * <cite>as-is</cite> under the {@code HREF} key.</p>
 *
 * @param  authority  the authority for which to set the code.
 * @param  code  the new code for the given authority, or {@code null} for removing the entry.
 * @return the previous code for the given authority, or {@code null} if none.
