List of nodeExists() Examples

Examples of nodeExists()

java.util.prefs.AbstractPreferences.nodeExists()
Implements the nodeExists method as per the specification in {@link Preferences#nodeExists(String)}.
This implementation is very similar to {@link #node(String)}, except that {@link #getChild(String)} is used instead of {@link #childSpi(String)}. @param path the path name of the node whose existence is to be checked. @return true if the specified node exists. @throws BackingStoreException if this operation cannot be completeddue to a failure in the backing store, or inability to communicate with it. @throws IllegalArgumentException if the path name is invalid (i.e.,it contains multiple consecutive slash characters, or ends with a slash character and is more than one character long). @throws IllegalStateException if this node (or an ancestor) has beenremoved with the {@link #removeNode()} method andpathname is not the empty string ("").
java.util.prefs.Preferences.nodeExists()
Returns true if the named preference node exists in the same tree as this node. Relative path names (which do not begin with the slash character ('/')) are interpreted relative to this preference node.
If this node (or an ancestor) has already been removed with the {@link #removeNode()} method, it is legal to invoke this method,but only with the path name ""; the invocation will return false. Thus, the idiom p.nodeExists("") may be used to test whether p has been removed. @param pathName the path name of the node whose existenceis to be checked. @return true if the specified node exists. @throws BackingStoreException if this operation cannot be completeddue to a failure in the backing store, or inability to communicate with it. @throws IllegalArgumentException if the path name is invalid (i.e.,it contains multiple consecutive slash characters, or ends with a slash character and is more than one character long). @throws NullPointerException if path name is null. @throws IllegalStateException if this node (or an ancestor) has beenremoved with the {@link #removeNode()} method andpathName is not the empty string ("").
javax.jcr.Session.nodeExists()
org.apache.felix.prefs.PreferencesImpl.nodeExists()
We do not synchronize this method to avoid dead locks as this method might call another preferences object in the hierarchy. @see org.osgi.service.prefs.Preferences#nodeExists(java.lang.String)
org.apache.jackrabbit.core.SessionImpl.nodeExists()
@see javax.jcr.Session#nodeExists(String) @since JCR 2.0
org.apache.jackrabbit.mk.api.MicroKernel.nodeExists()
Determines whether the specified node exists. @param path path denoting node @param revisionId revision id, if {@code null} the current head revision is assumed @return {@code true} if the specified node exists, otherwise {@code false} @throws MicroKernelException if the specified revision does not exist or if another error occurs
org.apache.jackrabbit.mk.core.MicroKernelImpl.nodeExists()
org.eclipse.core.runtime.preferences.IEclipsePreferences.nodeExists()
org.eclipse.equinox.security.storage.ISecurePreferences.nodeExists()
org.eclipse.ui.internal.preferences.WorkingCopyPreferences.nodeExists()
org.elasticsearch.cluster.node.DiscoveryNodes.nodeExists()
org.jahia.services.content.JCRSessionWrapper.nodeExists()
org.osgi.service.prefs.Preferences.nodeExists()
Returns true if the named node exists. Accepts a relative or absolute pathname. Absolute pathnames (which begin with {@code '/'}) are interpreted relative to the root of this node. Relative pathnames (which begin with any character other than {@code '/'}) are interpreted relative to this node itself. The pathname {@code ""} is valid, and refers to thisnode itself.
If this node (or an ancestor) has already been removed with the {@link #removeNode()} method, it is legal to invoke this method,but only with the pathname {@code ""}; the invocation will return {@code false}. Thus, the idiom {@code p.nodeExists("")} may be used totest whether {@code p} has been removed. @param pathName the path name of the node whose existence is to bechecked. @return true if the specified node exists. @throws BackingStoreException if this operation cannot be completed dueto a failure in the backing store, or inability to communicate with it. @throws IllegalStateException if this node (or an ancestor) has beenremoved with the {@link #removeNode()} method and{@code pathname} is not the empty string ({@code ""}). @throws IllegalArgumentException if the path name is invalid (i.e., itcontains multiple consecutive slash characters, or ends with a slash character and is more than one character long).
