Examples with DefaultParameterDescriptorGroup org.apache.sis.parameter.DefaultParameterDescriptorGroup used on opensource projects

Example 11 with DefaultParameterDescriptorGroup

use of org.apache.sis.parameter.DefaultParameterDescriptorGroup in project sis by apache.

the class CC_OperationMethod method group.

/**
 * Wraps the given descriptors in a descriptor group of the given name. If the given name can be matched
 * to the name of one of the predefined operation method, then the predefined parameters will be used.
 *
 * <p>We try to use predefined parameters if possible because they contain information, especially the
 * {@link org.opengis.parameter.ParameterDescriptor#getValueClass()} property, which are not available
 * in the GML document.</p>
 *
 * <div class="note"><b>Note:</b>
 * this code is defined in this {@code CC_OperationMethod} class instead than in the
 * {@link DefaultOperationMethod} class in the hope to reduce the amount of code processed
 * by the JVM in the common case where JAXB (un)marshalling is not needed.</div>
 *
 * @param  name         the operation method name, to be also given to the descriptor group.
 * @param  descriptors  the parameter descriptors to wrap in a group. This array will be modified in-place.
 * @return a parameter group containing at least the given descriptors, or equivalent descriptors.
