----------------------------------
Summary: ObjectUtils.identityToString(Object) and friends should
allocate builders and buffers with a size
Key: LANG-1367
URL: https://issues.apache.org/jira/browse/LANG-1367
Project: Commons Lang
Issue Type: Improvement
Components: lang.*
Reporter: Gary Gregory
Assignee: Gary Gregory
ObjectUtils.identityToString(Object) and friends should allocate builders and
buffers with a size.
Calling ObjectUtils.identityToString(Object) will allocate a {{StringBuilder}}
and append to it. The {{StringBuilder}} will reallocate it's internal
{{char[]}} at least once since most strings end up being larger than the
default 16 characters initially allocated by a StringBuilder (on Oracle Java 7).
This change computes the strings parts first and then allocates a
{{StringBuilder}} of the right size.
Similarly, the {{identityToString}} methods that accept an existing
builder/buffer can call {{ensureCapacity}} to avoid any extraneous allocations.
