Usage

From source file:org.apache.axis.encoding.SerializationContextImpl.java

/**
 * Serialize the indicated value as an element with the name
 * indicated by elemQName./*from  w  w  w  .  j a v  a 2 s  .  c  o  m*/
 * The attributes are additional attribute to be serialized on the element.
 * The value is the object being serialized.  (It may be serialized
 * directly or serialized as an mult-ref'd item)
 * The value is an Object, which may be a wrapped primitive.
 * The xmlType (if specified) is the QName of the type that is used to set
 * xsi:type.
 * The sendNull flag indicates whether null values should be sent over the
 * wire (default is to send such values with xsi:nil="true").
 * The sendType flag indicates whether the xsi:type flag should be sent
 * (default is true).
 * @param elemQName is the QName of the element
 * @param attributes are additional attributes
 * @param value is the object to serialize
 * @param xmlType is the qname of the type or null.
 * @param sendNull determines whether to send null values.
 * @param sendType determines whether to set xsi:type attribute.
