Field Detail

xQueryString

protected java.lang.String xQueryString

Constructor Detail

XQueryInteraction

public XQueryInteraction()

Default constructor.

XQueryInteraction

public XQueryInteraction(java.lang.String xQueryString)

Construct the interaction with the XQuery string.

Method Detail

getXQueryString

public java.lang.String getXQueryString()

PUBLIC: Return the XQuery string.

setXQueryString

public void setXQueryString(java.lang.String xQueryString)

PUBLIC: Set the XQuery string.

getQueryString

public java.lang.String getQueryString()

INTERNAL: Return the query string.

Specified by:

getQueryString in interface org.eclipse.persistence.internal.databaseaccess.QueryStringCall

Overrides:

getQueryString in class org.eclipse.persistence.internal.databaseaccess.DatasourceCall

setQueryString

public void setQueryString(java.lang.String queryString)

INTERNAL: Set the query string.

Specified by:

setQueryString in interface org.eclipse.persistence.internal.databaseaccess.QueryStringCall

Overrides:

setQueryString in class org.eclipse.persistence.internal.databaseaccess.DatasourceCall

translate

public void translate(org.eclipse.persistence.internal.sessions.AbstractRecord translationRow,
                      org.eclipse.persistence.internal.sessions.AbstractRecord modifyRow,
                      org.eclipse.persistence.internal.sessions.AbstractSession session)

INTERNAL: Allow the call to translate the XQuery arguments.

Specified by:

translate in interface org.eclipse.persistence.internal.databaseaccess.QueryStringCall

Overrides:

translate in class EISInteraction

createInputDOM

public org.w3c.dom.Element createInputDOM(EISAccessor accessor)

Create a DOM for this interaction. Convert the database row or arguments into an XML DOM tree. Handles arguments different as the XQuery and input can both have parameters.

Overrides:

createInputDOM in class XMLInteraction

prepare

public void prepare(org.eclipse.persistence.internal.sessions.AbstractSession session)

INTERNAL: Translate the custom query markers.

Specified by:

prepare in interface org.eclipse.persistence.internal.databaseaccess.QueryStringCall

Overrides:

prepare in class XMLInteraction

getLogString

public java.lang.String getLogString(org.eclipse.persistence.internal.databaseaccess.Accessor accessor)

Return the string for logging purposes.

Specified by:

getLogString in interface Call

Overrides:

getLogString in class XMLInteraction

argumentMarker

protected char argumentMarker()

INTERNAL: Return the character to use for the argument marker. ? is used in SQL, however other query languages such as XQuery need to use other markers.

Overrides:

argumentMarker in class org.eclipse.persistence.internal.databaseaccess.DatasourceCall

whitespace

protected java.lang.String whitespace()

INTERNAL: Return the characters that represent non-arguments names.

Overrides:

whitespace in class org.eclipse.persistence.internal.databaseaccess.DatasourceCall

isQueryStringCall

public boolean isQueryStringCall()

Specified by:

isQueryStringCall in interface org.eclipse.persistence.internal.databaseaccess.QueryStringCall

Overrides:

isQueryStringCall in class org.eclipse.persistence.internal.databaseaccess.DatasourceCall
