Exceptions

EvioException if newChild is null, or this node does not allow children.

std::vector< std::shared_ptr< BaseStructure > >::iterator evio::BaseStructure::childrenBegin ( )

inherited

Creates and returns a forward-order begin iterator of this node's children.

Modifying this node's child array invalidates any child iterators created before the modification. Originally part of java's DefaultMutableTreeNode.

Returns: a begin iterator of this node's children.

std::vector< std::shared_ptr< BaseStructure > >::iterator evio::BaseStructure::childrenEnd ( )

Creates and returns a forward-order end iterator of this node's children.

Modifying this node's child array invalidates any child iterators created before the modification. Originally part of java's DefaultMutableTreeNode.

Returns: an end iterator of this node's children.

References evio::BaseStructure::children.

uint32_t evio::BaseStructure::dataLength ( )

protectedinherited

Compute the dataLength in 32-bit words.

This is the amount of data needed by a leaf of primitives. For non-leafs (structures of structures) this returns 0. For data types smaller than an int, e.g. a short, it computes assuming padding to an integer number of ints. For example, if we are writing a byte array of length 3 or 4, the it would return 1. If the byte array is 5,6,7 or 8 it would return 2;

Returns: the amount of 32-bit words (ints) needed by a leaf of primitives, else 0.

Referenced by evio::BaseStructure::writeQuick().

std::vector< signed char > & evio::BaseStructure::getCharData ( )

inherited

Gets the raw data as an signed char vector, if the contents type as indicated by the header is appropriate.

If the returned vector's data is modified, then updateCharData MUST be called!

Returns: the data as an signed char vector, or null if this makes no sense for the given contents type.

std::shared_ptr< BaseStructure > evio::BaseStructure::getChildAfter ( const std::shared_ptr< BaseStructure > aChild )

inherited

Returns the child in this node's child vector that immediately follows aChild, which must be a child of this node.

If aChild is the last child, returns null. This method performs a linear search of this node's children for aChild and is O(n) where n is the number of children; to traverse the entire vector of children, use an iterator instead. Originally part of java's DefaultMutableTreeNode.

Parameters

aChild child of this node which immediately precedes the returned child structure.

std::vector< std::string > & evio::BaseStructure::getStringData ( )

inherited

Gets the raw data (ascii) as an vector of string objects, if the contents type as indicated by the header is appropriate.

For any other behavior, the user should retrieve the data as a bytes and manipulate it in the exact manner desired. If there are non ascii or non-printing ascii chars or the bytes or not in evio format, a single string containing everything is returned.

Originally, in evio versions 1, 2 and 3, only one string was stored. Subsequent changes allowed a vector of strings to be stored and retrieved. The changes are backwards compatible.

The following is true about the string raw data format:

Each string IS immediately followed by an ending null (0).
All string data are further padded/ended with at least one 0x4 valued ASCII char (up to 4 possible).
The presence of 1 to 4 ending 4's distinguishes the recent string array version from the original, single string version.
The original version string may be padded with anything after its ending null.

Returns: the data as a vector of string objects if DataType is CHARSTAR8, or null if this makes no sense for the given type.

void evio::BaseStructure::transform ( std::shared_ptr< BaseStructure > const & structure )

inherited

This method does a partial copy and is designed to help convert between banks, segments,and tagsegments in the StructureTransformer class (hence the name "transform").

It copies all the data from another BaseStructure object. Children are not copied in the deep clone way, but their references are added to this structure. It does not copy header data or the parent either.

Parameters

structure BaseStructure from which to copy data.

std::string evio::BaseStructure::treeToString ( std::string const & indent ) const

inherited

Recursive method to obtain a string representation of the entire tree structure rooted at this structure.

Parameters

indent string containing indentation for this structure. Generally called with "".

Returns: a string representation of the entire tree structure rooted at this structure.
