Description
EHeapException is the exception class for errors related to heap-allocated memory. {{#multireplace:System.SysUtils.EInvalidPointer|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}} inherits from {{#multireplace:System.SysUtils.EHeapException|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}}. All content below this line refers to {{#multireplace:System.SysUtils.EHeapException|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}}.
EHeapException is the exception class for errors related to heap-allocated memory.
EHeapException's descendants—EOutOfMemory and EInvalidPointer—are used to handle failed allocations of dynamic memory and invalid pointer operations.
Note: Memory for these exceptions is pre-allocated whenever an application starts and remains allocated as long as the application is running. Never raise EHeapException or its descendants directly.
